Hi, I am not sure where to post this to be honest as there isn't a dedicated thread for controllers... in any case I am going to post in the hope someone can help! I bought 2 Scythe Kama Meters, I have 7 fans that need attaching. I put 3 fans on one controller and 4 on the other, with associated temperature probes. Everything installed and worked OK, but after about 10 minutes or so the controller with the 4 fans stopped working and the display turned black. I unplugged everything and just had it plugged on it's own via power cable and still nothing (with no fans or temp probes). So I put in an RMA for another from scan.co.uk and it arrived today... unfortunately the exact same thing has happened. This is driving me crazy hehe. Where am I going wrong here? The first one with the 3 fans is still working fine, I just can't seem to get the second one to work. Each fan is identical, the rated voltage for each is DC 12V, maybe 4 of those is too much for the controller and I have blown something inside? Or maybe I am not supposed to use 2 controllers in a PC, but each controller has it's own dedicated power lead coming off the PSU. So it is not sharing power from other devices from the same lead. I am going to call Scan again but thought I would try here first. I really like the controller but if it doesn't work I may have to find a different one for the other 4. Thanks in advance. Motoko
